Eric Barnes[email protected]CTARRS: CT useful when abdominal US is inconclusiveAbout a third of CT exams performed after inconclusive abdominal ultrasound are positive, making CT a good choice for follow-up in many patients, researchers said on Monday at the American Roentgen Ray Society (ARRS) meeting in Vancouver.April 29, 2012CT320-row CT cuts pediatric radiation dose versus 64-slice imagingPediatric radiation dose was cut by as much as half for some clinical applications by swapping 64-detector-row CT for 320-detector-row scanning, according to researchers from Cincinnati Children's Hospital Medical Center. The study indicates that advances in CT technology can be successfully used to cut pediatric radiation dose.April 29, 2012CTNEJM: Low-dose CT good enough to diagnose appendicitisLow-dose CT is nearly equivalent to the standard-dose scan for diagnosing appendicitis, and it's accurate enough to serve as a first-line diagnostic modality while delivering less than one-fourth the radiation dose of full-strength CT, researchers report in a study published in the April 26 New England Journal of Medicine.April 24, 2012CTStudy shows more kids having CT for abdominal painCT use has continued to rise for young patients who visit the emergency department for nontraumatic abdominal pain, according to a new study published online April 24 in Radiology.April 23, 2012CTCocaine use linked to mixed coronary plaque on CTCocaine users are known to have higher-than-normal rates of acute coronary syndrome compared to others at risk of heart disease. Researchers from the Medical University of South Carolina used dual-source CT to learn more about how cocaine use affects the development of coronary atherosclerosis.April 23, 2012CTAmerican Lung Association supports CT screening for smokersBased on mounting evidence that lung cancer screening with CT can save lives, the American Lung Association on Monday recommended CT lung cancer screening for smokers and former smokers. The move is a major step toward the development of a population-based CT screening program in the U.S.April 22, 2012CTPediatric CT dose reduction lags in community hospitalsSAN FRANCISCO - A decade into worldwide dose reduction efforts, most community hospitals and imaging centers still haven't adopted low-dose CT techniques, according to a study presented on Thursday at the 2012 Society for Pediatric Radiology meeting.April 19, 2012CTAuntMinnie.com CT InsiderApril 18, 2012CTMost CTPA scans are negative even in highest-risk populationThe scan radiologists love to hate can be a lifesaver. Yet most CT pulmonary angiography (CTPA) scans for suspected pulmonary embolism (PE) come up negative, even in the population that might be expected to have the greatest risk: patients presenting to the emergency department with symptoms suggestive of PE.April 17, 2012CTVC CAD shows high accuracy for flat-lesion detectionA computer-aided detection (CAD) technique for virtual colonoscopy detected hard-to-find flat colorectal polyps with equivalent sensitivity it attained for polypoid lesions in the same patients, according to researchers from Boston.April 17, 2012Previous PagePage 87 of 258Next PageTop StoriesMolecular ImagingExperts issue appropriate use criteria for molecular breast imagingThe criteria offer use scenarios for technetium-99 (Tc-99m) sestamibi-based gamma camera imaging of the breast.MRIfMRI: Cognitive behavioral therapy positively affects the brainPractice ManagementPost Cures Act, outpatients access radiology reports fasterMRIMRI may help guide brachial plexus surgeryAIShould hospitals pursue local domain LLM adaptation for radiology reports?
